请到 App Store 更新到最新版后重开。若仍异常，重启 iPhone 再试。光灯需要 iOS 17 或更高版本。启动后整块屏幕就是补光，不需要再点「开始」。
Update from the App Store and reopen. If it still fails, restart the iPhone. The app requires iOS 17 or later. After launch the whole screen is the light; there is no separate Start button.
打开即补光。底部左侧是色温，右侧是亮度。右上角半圆按钮打开主题面板。没有账号，也没有设置页。
It lights as soon as it opens. The left slider is color temperature, the right slider is brightness. The half-circle button at the top-right opens themes. There is no account and no settings screen.
界面语言跟随 iPhone 系统语言，App 内没有语言开关。本网站可用右上角「中 / EN」切换。
The app follows the iPhone system language. There is no in-app language switch. This website can switch with 中 / EN.
目前只有 iOS。请从 App Store 下载，App ID 6811735744。
iOS only for now. Download it from the App Store, app ID 6811735744.
在补光页把亮度滑条拉高，并保持 App 在前台。系统自动亮度或低电量模式可能压低观感，可在「设置 › 辅助功能 / 显示与亮度」里临时关闭自动亮度后再试。
Raise the brightness slider and keep the app in the foreground. Auto-Brightness or Low Power Mode can dim the look. Temporarily turn off Auto-Brightness in Settings, then try again.
回到主屏幕、切到后台或划掉 App 时，光灯会把系统亮度恢复为进入前的状态，避免把补光亮度留在系统里。
When you go Home, background the app, or swipe it away, Jiguang restores the system brightness from before you opened it, so the fill-light level is not left behind.
滑向一侧更冷，另一侧更暖，作用在当前主题的底色上。和亮度一样，调节后会立刻保存在本机。
One end is cooler, the other is warmer. It tints the current theme. Like brightness, changes are saved on device immediately.
免费主题（柔白日光、夜拍暖光）点「使用」即可。带锁的主题需解锁 Pro；可先预览，点「预览 · 需 Pro」或「使用」会进入购买。
Free themes (Soft Daylight, Night Warm Light) apply when you tap Use. Locked themes need Pro. You can preview first. Tapping the locked action opens the purchase sheet.
不会。预览只在当前面板有效。不点「使用」就关掉面板，会回到原来的主题。
No. Preview lasts only while the panel is open. Dismiss it without Use and the previous theme returns.
免费：柔白日光、夜拍暖光。Pro：白天冷光、柔粉氛围、舞台追光、电影暖调、冷白柔光、阳光暖黄、柔光米白。与 App 内名称一致。
Free: Soft Daylight, Night Warm Light. Pro: Day Cool Light, Soft Pink Mood, Stage Spotlight, Cinematic Warm, Cool White Light, Sunny Warm, Soft Ivory. Names match the app.
不会。Pro 是一次买断的非消耗型商品，不是订阅。价格以 App Store 购买框的 StoreKit 价格为准，网站不写死金额。
No. Pro is a one-time non-consumable, not a subscription. The App Store sheet shows the StoreKit price. This site does not hard-code an amount.
确认网络正常，用你的 Apple ID 完成系统购买框。若你点了取消，App 会提示「已取消」。真正失败会提示「购买没成功，再试一次」。仍不行：退出 App Store 账号后重登，或稍后再试。
Check the network and complete the system purchase sheet with your Apple ID. Cancel shows “purchase cancelled”. A real failure shows “purchase didn’t go through, try again”. Still stuck: sign out of the App Store and back in, or try later.
打开光灯 › 右上角主题 ›「解锁全部主题」或任意锁定主题 › 在购买半屏点「恢复购买」。必须使用购买时的同一个 Apple ID。
Open the app › themes (top-right) › Unlock all themes or any locked theme › tap Restore Purchases on the sheet. Use the same Apple ID that bought Pro.
这通常出现在「购买前询问」（Ask to Buy）或家庭共享场景。请让批准人在其设备上处理请求。批准前主题不会解锁。
This usually means Ask to Buy or Family Sharing. The approver must handle the request on their device. Themes stay locked until it is approved.
购买成功后会提示「已解锁，主题可用了」，锁定会解开。若当时在预览某个 Pro 主题，仍需再点「使用」才会保存该主题。
Success shows that Pro is unlocked and themes are ready. Locks are removed. If you were previewing a Pro theme, tap Use once more to save that theme.
不收集个人数据，也不需要相机或相册权限。补光与主题都在设备本地完成。光灯不是相机 App，也不会美颜或读取照片。详见隐私政策和用户协议。
We do not collect personal data and do not need camera or photo library access. Lighting and themes stay on device. This is not a camera and does not beautify or read photos. See the Privacy Policy and Terms of Use.
